Smart Raspberry Based GSM Gateway

摘要

Mobile telecommunications systems face nowadays-rapid increasing services based on the third and new generations. This emergence influences the offered services as well as related costs. It is interesting to have reduced communications charges within an institution. One solution consists to use Gateways ensuring an intelligent management for outgoing calls by selecting the appropriate operator and telecommunication services to deal with best price selection. In this work, we are building low-cost smart GSM gateway based on Raspberry Pi and Microsoft .NET technologies to allow institutional or companies intranet networks to communicate via one of the local Algerian national operators.
